Can be used in expressway, main road, first-class and second class highway. ? Ultra-slim die-casting integrated lamp, streamline, thin,blazonry, burliness and durability. ? Using high thermal conductivity magnesium alloy material, match with around vents thermal conductivity, can be distributed quickly and ensure the LED lifetime. ? Shiny surface with using high-strength and ultra white tempered glass, high intensity, acid and alkali resistant, anti UV, not sticky ash and self-cleaning. ? Using bat wings or cluster type light distribution design to realize low glare and uniform illumination. ? Built-in whole lamp plate, modular design lens, simple circuits and quickly assemble. ? Independent power supply cavity design and without any outside interference by the outside environment. ? Suitable for high humidity, high and low temperature of the outdoor environment. ? Since using the low density magnesium alloy material for the whole lamp, the overall weight is lighter with ultra-thin design and enable to withstand the influence of cross wind. ? LED use no eutectic crystal line Eutectic welding technology, no crystal line needed for welding to avoid the compression open hidden trouble for LED. ? Unique series and parallel design for the lamp PCB board, the whole light irradiation effect will not be affected even one of the LED open circuit. ? From the thermal, electrical and material to assess the design, products can work normally within - 40 ~ 50 degrees. ? Human ergonomics light distribution makes full use of the characteristics of human eye to the brightness sensitive and unable to detect intensity of illumination. Using the equivalent brightness light distribution design to meet to the road design requirements. ? Impact resistance, earthquake resistant capability is strong, no ultraviolet and infrared radiation. ? Significantly energy saving significantly, over 60% energy saving compared to conventional light with similar lumen output.
